Recent Discoveries

Gulf of Mexico

Rio Grande (Big Bend - 2012, Troubadour - 2013, Dantzler - 2013)

The Company’s most recent success in the deepwater Gulf of Mexico comes from the Rio Grande project, with three field discoveries planned for development.  Big Bend, a significant oil discovery, has been approved for development, with first oil production targeted for late 2015.  Following Big Bend, the Troubadour natural gas discovery and Dantzler oil discoveries confirmed additional hydrocarbons for development.  Dantzler is planned for first production in 2016.

Gunflint (2008)

The Gunflint discovery represents another large discovery in the deepwater Gulf of Mexico. Drilled on Mississippi Canyon Block 948, we generated this subsalt Miocene prospect and acquired the lease at the March 2006 OCS Sale 198.  Appraisal drilling has confirmed significant oil quantities and the Company approved Gunflint for development in 2013.  First oil is planned for 2016 as a subsea tieback to existing infrastructure. 

Galapagos (Isabela - 2007, Santa Cruz - 2009, Santiago - 2011)

At Mississippi Canyon 519 and 562, we discovered 130 MMBoe of gross resources at the Isabela, Santa Cruz and Santiago fields.  The Galapagos development was sanctioned in 2009 as a subsea tieback to nearby infrastructure.  First oil production from the upper and middle Miocene discoveries was achieved in July 2012.


Cyprus A (2011)

The natural gas discovery in Cyprus Block 12 has estimated gross mean resources of 5 trillion cubic feet (Tcf).  The discovery well encountered substantial net natural gas pay in multiple high-quality Miocene sand intervals.  At the time of discovery, it was the fifth consecutive natural gas field discovery for the Company in the Eastern Mediterranean.  Additional exploration is planned for the Block 12 area offshore Cyprus.


Leviathan (2010)

The largest exploration discovery in our history, Leviathan, with 19 Tcf of gross natural gas mean resources, represented the largest deepwater natural gas discovery in the world over the past decade. Noble Energy and partners are evaluating the monetization options at Leviathan, including various LNG and pipeline export opportunities, as well as tie-in to Israel to meet growing domestic demand.  A Memorandum of Understanding was recently signed to bring Woodside into the Leviathan partnership.  Following completion of the transaction, Noble Energy will have a 30 percent operated working interest. The first phase of development at Leviathan is anticipated to be approved in 2014.

Tamar (2009)

The Tamar natural gas discovery was the largest conventional gas discovery in the world in 2009. Drilled in a highly under-explored area of the Mediterranean Sea, the well encountered multiple high-quality reservoirs.  Appraisal work, including drilling and core sample analysis, has determined gross mean resources of 10 Tcf of natural gas.  Production at Tamar commenced in March 2013, with strong performance and reliability since start-up in meeting Israel’s natural gas demand.  We operate the Tamar development with a 36 percent interest.

Tamar Southwest (2013)

The Tamar Southwest discovery is a separate field with approximately 700 billion cubic feet of natural gas resources.  The discovery was approved for development in late 2013 as a subsea tieback to existing infrastructure at Tamar.

Other discoveries offshore Israel include Dalit, Dolphin, Tanin and Karish.  Total combined discovered resources for all of the Company’s Eastern Mediterranean fields are approximately 40 trillion cubic feet of natural gas. 

West Africa

Noble Energy’s exploration successes in West Africa began in 2005 with the Alen gas-condensate discovery in Block O. Since that time, we have been actively engaged in offshore exploration in Equatorial Guinea (EG), with operated working interests of 45 percent in Block O, 38 percent in Block I, and 50 percent offshore Cameroon in the YoYo mining concession and Tilapia exploration block.  To-date, we have identified a number of oil and gas-condensate reservoirs, including:

  • Alen – gas-condensate (Block O – EG) - formerly known as Belinda
  • Aseng – oil (Block I – EG) - formerly known as Benita
  • Yolanda – gas-condensate (Block I – EG)
  • Felicita – gas-condensate (Block O – EG)
  • Diega – oil and gas-condensate (Blocks O & I – EG) - formerly known as Carmen
  • YoYo – gas-condensate (YoYo mining concession – Cameroon)
  • Carla – oil discovery (Block O – EG)

The first project was the Aseng FPSO development, which came on line seven months ahead of schedule in November 2011.  Following Aseng, the Alen gas-condensate project started up in mid- 2013, utilizing the Aseng FPSO infrastructure.  We are actively appraising and progressing additional discoveries, including Diega and Carla for future development.  In addition, we are working with a number of parties to further the gas monetization discussions for other discoveries.
